What set of elements has similar properties?

Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.

Which of the following have similar chemical properties?

Isotopes of an atom have similar chemical properties as they have same atomic number and different atomic masses.

What property of an element determines its chemical Behaviour?

Answer. Answer: Atomic number . The number of electrons and protons in an atom determines it’s chemical properties..

Which of the following classes of elements differ in their chemical properties?

Both isotopes and isobars differ in their chemical properties.

What group number is actinides?

The Actinide series contains elements with atomic numbers 89 to 103 and is the sixth group in the periodic table. The series is the row below the Lanthanide series, which is located underneath the main body of the periodic table.

Which is a metalloid?

The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. Five elements are less frequently so classified: carbon, aluminium, selenium, polonium, and astatine.

Which pair of element has the same characteristic chemical properties?

These are the first 20 elements in the periodic table. For example, pairs lithium (Li) and magnesium (Mg), beryllium (Be) and aluminium (Al), boron (B) and silicon (Si), etc are exhibiting similar properties. Boron and Silicon are both semiconductors. Thus Magnesium and Lithium have similar properties.

Why do two Isotopes have the same chemical properties?

Atoms of the same element that differ in their numbers of neutrons are called isotopes. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.

Which pair of properties describes the elements in group 18?

The noble gases are a group of chemical elements that make up Group 18 on the periodic table. These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity.

Which pair of elements are in the same period?

Sodium and chlorine are in same period.

What is the family name for Element B?

Disagreements mostly involve elements number 1 and 2 (hydrogen and helium), as well as inner transition metals. Groups may also be identified using their topmost element, or have a specific name….Group names.

New IUPAC name Group 13
Old IUPAC (Europe) IIIB
CAS name (U.S.) IIIA
